High pressure builds in today but then retreats slightly north this weekend. While this is occurring, Ian makes one more landfall as a hurricane (category 1) on the South Carolina coast today then moves north northwest into the mountains of North Carolina and Virginia where it weakens over the weekend. We’ve already experienced the high cloud shield from Ian for over 24 hours – it made for a very colorful sunset for some areas yesterday and a nice sunrise for some again this morning. The rainfall from that system is also spreading out and some of it will make a push toward our area for this weekend. The question for several days has been just how much impact, if any, that rain would have. Even when it became clear the low itself would not make the trip directly up this way, we always have to watch for the rain shield in this pattern as it can move quite a distance away from its parenting storm. Right now the best guess is that there will be the most rain right along the South Coast on Saturday, with a lesser chance that rain gets to and north of I-90, and if it does so it would be rather brief and lighter, before moving out. Either way, the cloud shield will be over the region much of the time the next few days, thin enough today that we have some filtered sunshine, but thicker so we have much less sun opportunity tomorrow (with the rain chance present) and maybe thinning out again at least to the north on Sunday. With a northeasterly air flow taking over between Ian’s remnant low and a big high to our north, we may eventually see some lower clouds from the ocean as well at some point during the weekend. Early next week we may still be on the fence as a hang-back low moves out south of our area, and may get close enough later Monday or Tuesday to bring some additional at least light rainfall in to parts of southeastern New England. All the while our temperatures will be running a little below normal as our cooler early autumn regime continues.
